As you know, I see my subconscious as a entity separate from myself. Viewing my subconscious from this perspective for many years and observing his astonishing talents when it comes to dealing with the world, I suspect he is aware of things going on that don't even touch me on a conscious level.

I am suggesting that your subconscious saw the Jeep and knew the danger of stepping off the bus! You just were not aware of it on a conscious level. I have had my hand jump out and catch something before I even knew I had dropped it.
